Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement needs that require the use of variable frequency water supply, it is recommended to prioritize checking key parameters such as head and flow range to ensure compatibility with the on-site pipeline system. Industrial circulating water scenarios typically require higher pressure stability.
  • When selecting suppliers, reference can be made to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. For example, suppliers who have long served municipal water supply projects may be more familiar with the requirements of multi pump group collaborative control.
  • In the secondary water supply scenario of high-rise buildings, attention should be paid to the response speed and energy-saving efficiency of the frequency converter. Some branded equipment can achieve a constant pressure accuracy of ± 0.01MPa through PID regulation.
  • When purchasing, the water fluctuation characteristics of different scenarios such as agricultural irrigation or industrial parks can be combined to compare the smoothness of frequency conversion curves for different models, in order to avoid motor losses caused by frequent start stop.

Knowledge Base

Q

This article analyzes the core requirements of the constant pressure water supply system for frequency converters, including precise pressure control, energy-saving characteristics, and system compatibility. It helps users choose suitable frequency converters to achieve stable and efficient water supply solutions.

Q

The core is "closed-loop constant voltage control", which achieves dynamic balance through the collaboration of four major components. The equipment consists of a pressure sensor, a frequency converter, a PLC control cabinet, and a water pump unit. The pressure sensor is installed at the outlet of the water supply network to monitor the pressure in real time and convert it into a 4-20mA electrical signal for feedback to the control cabinet. PLC compares the actual pressure with the set value through PI
